Bet you can get one cheap over there m8
Excellent idea to have this bit of kit as part of your test equipment. Much cheaper than a Thermal Imager, but then your talking substantially more, ....even for a basic set-up job.
These IR thermometers are another tool in your arsenal to successful fault finding. Often when there are no visual clues as to what's going on within components and equipment, invaluable in those conditions...
